Find out what spices were used

I have recently been ordering food from a place that has a fried rice that I like a lot. A lot a lot. The ingredients are pretty basic, which makes me think that the spices used in this dish are what makes it taste so incredibly good (though of course things like the method of preparation may also matter quite a bit).

I should really go to the restaurant and ask them about this dish. However, this does make me wonder:

Is there a way for me to take a prepared batch of this dish and find out what spices were used? The spices I do not know yet are the ones I care about the most.

(I'm very much afraid the answer will simply be no, but it doesn't hurt to ask, does it?)
